Description : What weight of Na will contain the same number of atoms as are present in 2.4 gm of carbon? -Chemistry 9th
Last Answer : 1 mole of Carbon has weight 12g. So 0.2 mole of Carbon will have weight 2.4 g. Now, 1 mole of Carbon contains 6.022 10^23 atoms So 0.2 moles of Carbon contains 1.2044 10^23 atoms. So we need to find the weight ... of Na. 1 mole of Na = 23 g So 0.2 mole of Na = 4.6 grams So, answer is 4.6 grams.
